You're absolutely right. However, I usually tackle the ugliest detail first. If
you compare Movie 1 and Movie 2, you'll see that the flame of the main engine
was even uglier.
See:

For the boosters I think of something completely different, thick fat smoke
plume, a lot of work :(

Same problem, ugliest parts first.
I quickly conjured up the solar cells and put more emphasis on the movements.

Textures and details are my biggest weakness anyway. It's just very tedious in
Povray to change a texture a bit, render, see what has happened, change again,
look... Wish there was a better way, or a tool.

Yes, its on my list.
Its to clean and smooth, will work on it.

Thanks for the links! Especially the first one, the tutorial is very helpful.
You will hardly believe it, but I have tried clouds in the last few days, see
result in the picture. Several clouds in side view and from above, with slight
changes.

You forgot about 100 points :)
I have so many ideas what to do.
I could work on it for the next years.
